Fuel Storage Kit (Boat + PWC)

Stale fuel is the number-one reason a boat won't start in May. Ethanol-blend gas starts separating and gumming carburetors and injectors in as little as 30 days. This kit treats a full boat tank and a PWC tank for the whole winter, plus a fuel-system cleaner for the last run of the season.

What's in the box

• STA-BIL Marine, 32 oz — treats up to 320 gallons. Enough for the boat's tank this fall with plenty left for spring. Fights ethanol water absorption and corrosion.
• STA-BIL 360 Marine, 8 oz — the small bottle for the Sea-Doo, jet ski or kicker tank. Vapour technology protects the fuel system above the fuel line too.
• Sea Foam Marine Pro, 20 oz — run it through on the last outing to clean injectors and carb passages before they sit for six months.

How to use it

1. Last trip of the season: add Sea Foam Marine Pro to the tank and run the engine for 20+ minutes.
2. Fill the tank to about 90% (less air = less condensation) and add STA-BIL Marine at 1 oz per 10 gallons.
3. Run the engine 5–10 minutes so treated fuel reaches the injectors or carb.
4. Same for the PWC with STA-BIL 360 Marine.

What this kit does not replace: engine antifreeze in a sterndrive or inboard cooling system, fogging oil, and a lower-unit oil change. Those are on the free Ontario Boat Winterization Checklist. Ships together, tracked, across Canada and the US.
